This paper presents a new method of combined electromagnetic levitation and propulsion using a double sided pair of linear induction machines and a simple conductive sheet secondary. If the supply phase angle of one primary is modified with respect to that of the other, a controllable lift force can be developed on the conductive secondary and its load at any velocity or when stationary. Further, a resolution force is developed tending to drive the secondary into the center of the air gap, meaning that the system is inherently self-stabilizing without complex position feedback or control. This effect is studied and predicted using finite element analysis and then measured and confirmed using an experimental rig.

This paper presents a model for a prototype of electromagnetic guidance system applied in high-speed maglev trains to study the guidance force that is produced by electromagnets and the ferromagnetic rail. The mathematical modeling of such system is derived to find out transfer function and state space models. The electromagnetic guidance system is hardly non-linear and open loop unstable. It is linearized around the reference points using Taylor series expansion method in order to approximate the behaviour of the system for a small range around the operating points. Finally, based on the state space model the technique of pole placement controller is applied and tested for stabilizing the system. MATLAB scripts are provided for simulation and for plotting the results.

“…It is considered to be a very promising solution for the future transportation and many researches, such as principles analysis and modeling, have been done since 1934 when Hermann Kemper patented it. State-of-the-art of maglev train technologies including levitation, propulsion, guidance and transfer of energy to vehicle are investigated [1]. Leading by Germany, Japan and China, high speed maglev researches has been developed steadily till now.…”

-Magnetic fields (MF) generated both on board the vehicle and along the guideway provide levitation and propulsion forces. High speed maglev trains adopt electromagnet or superconducting magnet to realize levitation and propulsion functions. However, stray fields existing in passenger compartment and regions surrounding the vehicle and guideway have effect on passengers and environment. To investigate stray magnetic field effect, model of Transrapid and MLX are studied.
